And viruses, too! I am very curious to find out what sorts of bacteriophages are part of the picture. In general we have some sense that actively changing the ratios of different bacterial species (e.g. with antibiotics, or fecal transplants) can address some health problems - but it's possible that a targeted phage might be another way to accomplish that as well.
